How to use the @sentry/core.NoopTransport function in @sentry/core

protected _setupTransport(): Transport {
    if (!this._options.dsn) {
      // We return the noop transport here in case there is no Dsn.
      return new NoopTransport();
    }

    const transportOptions = {
      ...this._options.transportOptions,
      dsn: this._options.dsn
    };

    if (this._options.transport) {
      return new this._options.transport(transportOptions);
    }

    if (this._isNativeTransportAvailable()) {
      return new NativeTransport();
    }

    return new Transports.FetchTransport(transportOptions);
